In hexamethylphosphoric triamide, toluene-4-sulphonyl azide generally performs smooth diazo group transfer to β-dicarbonyl compounds, whereas 4-nitrophenyl azide can exhibit diazo transfer reaction with malonates and cyclic β-diones but leads to triazole formation with acyclic β-diones and β-keto esters.
